On the luminosity function of galaxies in groups in the Sloan Digital Sky Survey
Ariel Zandivarez, Hector J. Martinez, Manuel E. Merchan
Using galaxy groups identified in the Fourth Data Release of the Sloan Digital Sky Survey (SDSS), we compute the luminosity function for several subsamples of galaxies in groups. I…
Shapes of clusters and groups of galaxies: Comparison of model predictions with observations
D. J. Paz, D. G. Lambas, N. Padilla +1
We study the properties of the 3-dimensional and projected shapes of haloes using high resolution numerical simulations and observational data where the latter comes from the 2PIGG…
2dFGRS and SDSS Galaxy Group Density Profiles
Eugenia Diaz, Ariel Zandivarez, Manuel Merchan +1
We have analysed the distribution of galaxies in groups identified in the largest redshift surveys at the present: the final release of the 2dF Galaxy Redshift Survey and the first…
Properties of groups of galaxies in the vicinity of massive clusters
C. J. Ragone, M. Merchan, H. Muriel +1
This work analyses the properties of groups of galaxies in the surroundings of clusters. On the basis of a very large public Virgo Consortium Simulation, we identified systems of g…
Galaxy groups in the 2dF galaxy redshift survey: Large Scale Structure with Groups
Ariel Zandivarez, Manuel E. Merchan, Nelson D. Padilla
We use the 2dF Galaxy Group Catalogue constructed by Merchán & Zandivarez to study the large scale structure of the Universe traced by galaxy groups. We concentrate on the computat…
